Making the shortest light bursts leads to better understanding of nature
An attosecond is a ridiculously brief sliver of time - a scant billionth of a billionth of a second. This may seem too short to have any practical applications, but at the atomic level, where electrons zip and jump about, these vanishingly short timescales are crucial to a deeper understanding of science.

Read moreZeroing in on the best shape for cancer-fighting nanoparticles
As the field of nanomedicine matures, an emerging point of contention has been what shape nanoparticles deliver their drug or DNA payloads most effectively. A pair of publications from a team led by Paulo Decuzzi of The Methodist Hospital Research Institute's (TMHRI) Texas Center for Cancer Nanomedicine suggests these microscopic workhorses ought to be disc-shaped, not spherical or rod-shaped, when targeting cancers at or near blood vessels.
